First Test Results from the New Norwegian Lidar for Monitoring of Marine Resources
(ICES CM Documents;2004/R:42, Working paper, 2004)Following promising lidar test flights in 2002, Institute of Marine Research (IMR), Bergen in cooperation with NTNU University, Trondheim started the process of designing and building a new lidar to be ready by summer ... -
ICES coordinated acoustic survey of ICES divisions IIIa, IVa, IVb and VIa (North) 2003 Results
(ICES CM Documents;2004/R:32, Working paper, 2004)Six surveys were carried out during late June and July covering most of the continental shelf north of 52°N in the North Sea and to the west of Scotland to a northern limit of 62°N. The eastern edge of the survey area was ... -
Combined algorithms for detection of acoustic categories
(ICES CM Documents;2004/R:38, Working paper, 2004)There is a current desire to harvest marine resources by managing total marine ecosystems rather than single species of the ecosystems. By means of algorithms applied on high-quality multi-frequency acoustic data, species, ... -
The effective swept volume of a bottom trawl
(ICES CM Documents;2004/R:7, Working paper, 2004)The reaction of individual fish towards an approaching trawling vessel has previously been measured using target-tracking methods. In this paper these measured velocities are fitted to a deterministic mean behaviour ... -
Testing various geostatistical models to combine bottom trawl catches and acoustic data
(ICES CM Documents;2004/R:28, Working paper, 2004)The aim of the CATEFA project is to combine information on demersal fish stock abundance from acoustic and bottom trawl surveys. While acoustic data are collected continuously while the research ship is underway, it is ... -
Pinging down the food web: multi-frequency acoustic discrimination of jellyfish and fish
(ICES CM Documents;2004/R:6, Working paper, 2004)Jellyfish are gaining increasing prominence in many pelagic marine ecosystems worldwide. It has been argued that jellyfish-dominated communities will be the end-point in ecosystems perturbed by high fishing effort, and ... -
Studying the relationship between spatial fish distributions and trawl catches
(ICES CM Documents;2004/R:26, Working paper, 2004)We propose an approach for studying the relationship between spatial fish distributions and the distribution of numbers in trawl catches. Individual spatial fish distributions are derived from acoustics data collected with ... -
Pelagic occurrence of Greenland halibut (Reinhardtius hippoglossoides) studied by means of vertical longlines
(ICES CM Documents;2004/K:69, Working paper, 2004)In order to calculate reliable survey indices it’s important to know the dynamics of vertical distribution of a fish species. The vertical distribution of Greenland halibut (Reinhardtius hippogolossoides) cannot be studied ... -
Recommendations for the collection of multifrequency acoustic data
(ICES CM Documents;2004/R:36, Working paper, 2004)Traditionally, collection of acoustic data has been optimised for a single frequency, while requirements for the optimal combination of multifrequency data has been given less attention. Even though data manipulation can ... -
Prey-specific gastric evacuation of Norwegian spring spawning herring (Clupea harengus)
(ICES CM Documents;2004/P:39, Working paper, 2004)Gastric evacuation rates have earlier mainly been measured based on laboratory experiments. The aim of this study is to obtain information of gastric evacuation rates when the herring are feeding in their natural environment. ... -
Report of the Working Group on the Application of Genetics in Fisheries and Mariculture (WGAGFM) [3- 5 May, 2004, Hamburg, Germany]

Spatial migration pattern of deep-sea redfish (Sebastes mentella Travin) of the Norwegian-Barents population from survey data
(ICES CM Documents;2004/K:31, Working paper, 2004)Study of redfish migration by traditional tagging-methods faces great difficulties. The redfish taken onboard a vessel usually prove to be nonviable. A sharp hydrostatic pressure differential is lethal for the redfish ... -

Stock discrimination of horse mackerel (Trachurus trachurus) in the Northeast Atlantic and Mediterranean Sea: integrating the results from different stock identification approaches
(ICES CM Documents;2004/EE:19, Working paper, 2004)The goal of horse mackerel stock discrimination was tackled by integrating both established and innovative approaches such as genetic markers (allozymes, mtDNA, microsatellite DNA and SSCP), morphometry and parasites, ...
